A second-grade activity uses Elkonin boxes to write letters in boxes under pictures. Which phonics concept does this strategy most directly reinforce?

• A. Vowel teams
• B. Consonant blends
• C. Diagraphs
• D. Syllable counting

Answer: (A)

Elkonin boxes focus on phonemic awareness by mapping each spoken sound in a word to a box and to the letters that represent it. This helps students see that sounds can be represented by letters, and it highlights that sometimes two letters work together to make one sound—digraphs. When a word has a digraph, that single sound is treated as one unit in the sequence, with the appropriate letters placed together in one box (or represented as a single sound) while the other sounds get their own boxes. For example, a word containing a digraph like "sh" is taught as one sound /ʃ/ followed by the remaining sounds. This directly reinforces the idea that letters can pair up to form a single sound, which is the essence of digraphs. Vowel teams are a related idea but a specific case within digraphs; consonant blends involve multiple distinct sounds in sequence, and syllable counting focuses on dividing words into syllables rather than mapping each sound to a box.
